Which apparatus would measure 50cm3 of hydrochloric acid with the greatest accuracy

Describe the trends shown in the student’s results.

Match the method to the unit of rate of reaction

Describe the trends shown in the student’s results.

Measuring the gas produced, the mass lost, or the light transmitted are all ways of measuring the rate of reaction.

Describe to Jun a method he could use to measure rate of reaction, and an advantage of using this method.

Increasing the pressure of gases in a reaction will increase the rate of reaction.

Increasing the temperature of reactants increases the number of particles in the reaction.

There are five main factors that affect the rate of reaction.

For every 10°C temperature increase, the rate of reaction triples.

Collision theory states that particles must collide with enough energy in order to react.

The minimum amount of energy required for a successful collision is called the starter energy.

Different catalysts are needed for different reactions.

During a reaction, a catalyst gets used up and has to be replaced each time.

Catalysts are usually cheap transition metals.

What two pieces of measuring equipment is he going to use to capture gas is this experiment?

What pieces of equipment is best for measuring the volume of a liquid, like acid?

Which piece of equipment is he using to capture gas in the first method?

How often do you need to measure the gas produced?

The first time he did this, he used 2 mol/dm3. The second time time he is using 1 mol/dm3. Do you think it will be faster or slower?

What piece of equipment captures the gas in this second experiment?

What piece of equipment measures time for all his experiments?

What do both experiments level off at the same point?
